Consider the the reaction to form nitrosyl bromide (NOBr). The following two-step mechanism is proposed:
Step 1: NO (g) + Br2 (g) → NOBr2 (g)
Step 2: NOBr2 (g) + NO (g) → 2 NOBr (g)
What is(are) the formula(s) of the intermediate(s), if any. If you think there aren't any, write "none" as your answer.

To determine the formula(s) of the intermediate(s), we need to identify any species that are formed and consumed during the reaction steps. In this case, we have Step 1 and Step 2 proposed as the mechanism for the formation of nitrosyl bromide (NOBr).
Step 1: NO (g) + Br2 (g) → NOBr2 (g)
Here, NO (nitric oxide) reacts with Br2 (bromine gas), resulting in the formation of NOBr2. In this step, there is a combination of NO and Br2, and the product NOBr2 is formed.
Step 2: NOBr2 (g) + NO (g) → 2 NOBr (g)
In Step 2, the previously formed NOBr2 reacts with NO to form 2 molecules of NOBr. In this step, NOBr2 is consumed, and NOBr is produced.
Based on this mechanism, the presence of the intermediate species NOBr2 indicates that it is an intermediate in this reaction. Therefore, the formula of the intermediate is NOBr2.
In summary, the formula of the intermediate is NOBr2.
